Pitch: Mark out a square of 5 x 5 to 10 x 10 metres with four flat markers; depending on the level it can be made tighter.
Equipment: 4 flat markers, 2 balls.
Players: Three corners of the square are each occupied by one player, one corner stays free. The two players at the diagonally opposite corners each have a ball. A fourth player without a ball stands in the middle of the area.
